8. Multiples and Factors MULTIPLES )3.4.5, 6. etc., are counting numbers. Multiply each counting number by 2. You get, 2x1, 2x 2, 2x3. 2x4. 2x 5, 2x6. etc. =2,4, 6., 8, 10, 12, etc. First ten multiples of 2 Here 2, 4, 6. 8, 10, 12, etc.. are multiples of 2. 2, 4. 6, 8, 10. 2 is the first mutiple of 2. 12, 14, l6, 18, 20 4 is the second multiple of 2. of 2. The numbers that are multiples of 2 appear in the multiplication table get multiples of 3, multiplying each In the same way, mutiplying each counting number byon.3 we cOunting number by 4 we get multiples of 4 and so First ten multiples of 3 3, 6.9. 12, 15, 18, 21, 24, 27, 30 First ten multiples of 4 4,8, 12, 16, 20, 24, 28, 32, 36, 40 First ten multiplies of 5 5, 10, 15, 20, 25,30, 35, 40, 45, 50 First ten multiples of 10 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 Multiple of anumber = the number Xa counting number Common Multiples The mutiples of 2 are 2, 4 6 8 10. 12. etc. The multiples of 3 are 3.(6) 9, |12. I5, 18, etc. of 2 and 3. Similarly, 12 Clearly. 6 is a multiple of 2 as well as of 3. So 6 is a common multiple multiples of 2 and 3. 1S also a common multiple of 2 and 3. There are other common Two Simple Properties of Multiples Ix2 =2.:. 2 is a multiple of 2. |x3=3 3 is a multiple of 3. Ix8= 8.. 8 is a multiple of 8. 69  kngw that WeWe hgan We Iheretore, So, WeWe PRODUCT REMEMBERThe Ths, So.
